BEARING FOR SPINNING-SPINDLES.

SPECIFICATION forming part of Letters Patent No. 372,524, dated November 1, 1887,

Application filed May 524, 1887. Serial No. 239,193. (No model.)

To all whom, it may concern.-

Be it known that I, \VILLIAM F. DRAPER, of Hopedale, county of \Vorcester, and State of Massachusetts, have invented an Improvement in Bearings for Spinning-Spindles, of'

which the following description, in connection with the accompanying drawing, is a specification.

Thisinvention, relating to spindles and bearings, has for its object to improve the steadiness of rotation, under an unbalanced load, of aspindle of that class wherein that part of the spindle below the pointofattaehtnent with it of the whirl runs in bearings in a supporting-tube.

In this my invention the spindle below the point at which the whirl is attached to it has two independent bearings, the lower bearing constituting also astep and being rigid, while the upper bearing is movable, the spindle between the two bearings being of small diameter and unconfined by a hearing.

The drawing in vertical section illustrates my invention.

The rail A and the supporting tube or case 13, connected to it by a nut. O, are of usual construction. The spindle D (but partially shown) has attached to it the sleeve-whirl E, the latter surrounding the supporting-tube. The supporting tube or case contains a lower rigid bearing, a, which also constitutes a step for thespindle. The supporting-tube B above the lower bearing or step, a, is provided with a bearing, 12, which is free to move in the said supporting'tube as the pintle of the spindle vibrates or moves in its rotation with its unbalanced load.

As herein shown, the bearing b is composed of a spirally-wound flat strip of sheet metal, it fitting the spindle, and a spirally-wound wire, the coils of the wire fitting into or opposite the spiral space or channel left between the edges of the spirally-wound tlat strip of metal,such location of the parts permitting the spindle and flat strip surrounding it to move laterally by pressing the outer wire between the openings of the flat strip, as will be readily understood.

The movable upper bearing, 1), nearest the junction of the whirl with the spindle will in practice be restrained by a pin or projection, as 19, from rotating with the spindle.

I claim- The supporting tube or case and the spindle and its whirl, combined with a rigid lower bearing and with a loosely-held or movable bearing above it, both the said bearings being located in the supporting tube or case, and supporting the sides of the spindle below the point of attachment to it of the whirl, substantially as described.

In testimony whereof I havesigned my name to this specification in the presence of two subscribing witnesses.

WM. F. DRAPER.
